3 )前摄像头 306, 位于手机主体 302的正面, 通过旋转部件 308连接至手机主体 302, 其中, 旋转部件 308在手机主体 302的正面具有旋转起始位置, 在手机主体 302 的背面具有旋转终止位置, 前摄像头 306可通过旋转部件 308在旋转起始位置和旋转 终止位置之间进行旋转。 与相关技术相比较, 本发明的上述实施例在具有前后双摄像头的手机的基础上将 前摄像头设计为可旋转的摄像头, 使其能够旋转至手机背侧与后摄像头一起构成能够 拍摄立体图像的双摄像头拍摄系统。 通过可旋转摄像头的设计, 既保持前摄像头的视 频通话功能, 又对该前摄像头的功能进行了复用, 通过这种可旋转摄像头的设计解决 了相关技术中无法在一台手机上同时实现视频通话和立体图像拍摄的问题, 从而在不 增加硬件的情况下在一台手机上同时实现视频通话和立体图像拍摄等功能, 大大提高 了系统硬件资源的利用率。 本发明提供了多种旋转方式, 下面结合附图来描述不同的旋转方式下的旋转部件 与前摄像头的连接关系。 作为一种优选的方式, 如图 4所示, 旋转部件 308可以包括: 第一旋转轴 (水平 旋转轴) 3081, 设置在手机主体 302的顶部凹槽中, 与手机主体 302和前摄像头 306 连接, 并平行于手机主体的上边缘。第一旋转轴 3081在手机主体 302的正面具有旋转 起始位置, 在手机主体 302的背面具有旋转终止位置。 通过这种连接方式, 前摄像头 306可以绕水平旋转轴 3081在手机的正面和背面来回旋转。 作为另一种优选的方式, 前摄像头还可以绕垂直的旋转轴进行旋转。如图 5所示, 旋转部件 308可以包括: 第二旋转轴 (垂直旋转轴) 3082, 设置在手机主体 302的顶 部凹槽中, 与前摄像头 306连接, 并垂直于手机主体 302的上边缘; 支撑部件 3083, 连接至手机主体 302, 并垂直连接至第二旋转轴 3082。 当然, 对于旋转部件与前摄像头之间的连接结构, 本发明并不仅限于上述两种连 接方式, 只要能实现前摄像头在手机的正面和背面之间旋转的连接方式均应落入本发 明的保护范围之内。 进一步, 可旋转的前摄像头 306可以根据实际情况有多种旋转设计方式, 但是必 须保证以下设计条件: 前摄像头可以 180 ° 旋转至手机背面, 前摄像头的镜头中心线 的朝向与后摄像头平行且都垂直与手机平面, 同时, 从手机背面正视观察, 可旋转的 前摄像头和后摄像头还需要保持上下高度一致, 即两颗摄像头的中心连线与手机的上 边缘平行 (图 3-5中手机主体 302的上边缘, SP, 短边), 以保证使用双摄像头拍照系 统取景时, 拍摄目标的高度相同, 这样才能使双摄像头拍摄系统的公共视场范围取到 最大。 为了实现上述目的, 本发明提供了一种优选的前摄像头 306和旋转部件 308之间 的连接关系, 即, 当前摄像头 306在背面的旋转停止位置上时, 前摄像头 306的镜头 与后摄像头 304的镜头的中心线与手机主体的上边缘平行。 通过这种连接关系, 能够 在前摄像头旋转到背面与后摄像头构成双摄像头拍摄系统时保证双摄像头拍摄系统的 公共视场范围取到最大。 还需要说明的是, 如果拍照时手机横放, 那么在前后摄像头位置设置时, 需要保 证两颗摄像头中心连线与手机侧边缘平行 (图 3-5中手机主体 302的侧边缘, SP, 长 边)。 这种分类设计的好处是拍摄时, 两颗摄像头可以从左右两个方向进行图像捕捉, 符合人们对于双目视觉类系统的使用习惯。 为了实现上述目的, 本发明提供了一种优选的前摄像头 306和旋转部件 308之间 的连接关系, 即, 当所述前摄像头在所述背面的旋转停止位置上时, 所述前摄像头的 镜头与后摄像头的镜头的中心连线与所述手机主体的侧边缘平行。通过这种连接关系, 能够在前摄像头旋转到背面与后摄像头构成双摄像头拍摄系统时保证两颗摄像头可以 从左右两个方向进行图像捕捉, 符合人们对于双目视觉类系统的使用习惯, 从而使得 前后摄像头拍摄的图像的数据的准确性。 关于如何控制前摄像头 306通过旋转部件 308在手机主体的正面和背面之间进行 旋转, 本发明可以通过微电机来进行控制, 例如, 本实施例中的手机还包括: 微电机, 其与旋转部件 308连接, 设置为输出控制信号来控制旋转部件的旋转。 当然, 本发明 不仅限于此, 还可以通过手工来控制前摄像头 306通过旋转部件 308在手机主体的正 面和背面之间进行旋转。 进一步, 本发明还在手机内设置了距离探测装置, 其可以对前摄像头 306和后摄 像头 304的相对角度进行调整。 优选的, 如图 3所示, 该距离探测装置 312的位置位 于旋转终止位置与后摄像头 304之间, 设置为测量被摄物体距前摄像头 306和后摄像 头 304的距离, 并根据测量得到的距离控制前摄像头 306距后摄像头 304的位置。 在 本实施例中, 通过距离探测装置可以使前摄像头和后摄像头形成的角度关系更接近人 目艮, 使得前后摄像头拍摄到的图像数据更加准确, 这样使得在手机上显示出的图像信 息更加逼真。 进一步, 上述的前摄像头 306和后摄像头 304上设置有滤波片。 这样, 能够对拍 摄的图像信息进行进一步的控制。 此外, 本发明还在图像处理方面对原有的图像处理部件进行了改进, 改进后的部 件将前后摄像头拍摄的图像信息的分辨率调整成一致, 然后进行合成, 这样在不需要 额外增加特殊的立体图像处理部件就能完成立体图像的生成, 用户使用时也无需佩戴 专业的 3D眼镜, 从而进一步提高了系统硬件资源的利用率。 为了实现上述目的, 本发明提供了一种优选的图像处理部件, 与前摄像头 306和 后摄像头 304连接, 设置为接收前摄像头 306获取的第一图像信息和后摄像头 304获 取的第二图像信息, 将第一图像信息的分辨率与第二图像信息的分辨率调整成相同, 并将调整后的第一图像信息和第二图像信息进行合成。 此外,本发明还提供了一种优选的图像显示部件,与前摄像头 306和后摄像头 304 连接, 设置为在显示屏的第一区域上显示调整后的第一图像信息, 并在显示屏的第二 区域上显示调整后的第二图像信息。 为了更清楚地描述本发明所保护的手机, 下面进一步结合附图对各个功能模块进 行描述。 图 6是根据本发明实施例的一种可以立体摄影的手机的功能模块示意图。 如图 6 所示, 手机的功能模块包括: 可旋转的前摄像头(后文也称左侧摄像头) 306, 后摄像 头 304 (后文也称右侧摄像头), 双摄像头控制模块 602, 双摄像头图像显示模块 604, 摆动式立体图像合成模块 606(视为图像处理部件), 摆动式立体图像显示模块 608 (视 为图像显示部件), 手机 LCD显示屏 610, 其中, 双摄像头控制模块 602与前摄像头 306和后摄像头 304相连, 并与双摄像头图像显示模块 604和摆动式立体图像合成模 块 606相连, 摆动式立体图像显示模块 608与摆动式立体图像合成模块 606以及 LCD 显示屏 610相连, 双摄像头图像显示模块 604与 LCD显示屏 610相连。 图 7示出了图 6中的手机的工作流程图, 其包括如下步骤: 步骤 S702, 使用本发明拍摄摆动式立体图像时, 首先将用于视频通话的前摄像头 306旋转至手机主体 302的背面, 与后摄像头 304—起构成双摄像头拍摄系统。 步骤 S704,用户打开手机上拍摄立体图片的相关应用程序,开始立体图像的拍摄。 步骤 S706, 双摄像头控制模块 602分别启动并初始化两颗摄像头, 使摄像头进入 正常的工作状态, 输出预览图像。 步骤 S708,双摄像头图像显示模块 604通过双摄像头控制模块交叉地从前后摄像 头获取图像数据, 并在手机的 LCD显示屏 610上进行分屏显示, 其中, LCD显示屏 显示效果示意图如图 8所示, 上部显示左侧摄像头的预览图像, 下部显示右侧摄像头 的预览图像。 步骤 S710, 用户根据左右侧摄像头的预览画面决定取景空间, 确定后点击拍照键 确认拍摄。 步骤 S712,手机软件中的摆动式立体图像合成模块 606首先对获取的图像画面进 行分辨率调整, 通过对高分辨率图像降采样或者低分辨率图像插值, 使两幅图像的分 辨率大小一致, 以提高合成后的立体图像的效果。 步骤 S714, 手机软件中的摆动式立体图像合成模块 606(视为图像处理部件)将调 整后的两幅图像按照 GIF格式进行压缩, 配置文件头, 设置图像的切换速率, 写入文 件实体,将两幅静态图像合成为一幅动态 GIF图像,完成摆动式立体图像的制作过程。 步骤 S716, 手机软件中的摆动式立体图像显示模块 608 (视为图像显示部件) 对 合成后的摆动式 GIF动画文件在手机屏幕上进行回显。如果手机自身支持 GIF动画显 示, 该步骤可以省略, 直接使用手机自身的显示模块进行回显。 步骤 S718, 对动态立体图像进行回显的同时, 提示用户保存或者放弃所生成的立 体动画文件。 如果用户选择保存, 则将生成的 GIF动画文件存入手机的文件系统中, 返回步骤 S708重新预览。 如果用户选择放弃, 则直接返回步骤 S708重新预览。 步骤 S720, 当用户使用本发明完成立体图像拍摄之后, 退出手机应用程序, 双摄 像头控制模块停止摄像头工作, 使其进入待机模式。 整个手机拍摄立体图像的工作流 程结束。 在上述实施例中, 通过可旋转的前置摄像头, 可以使得手机在支持视频通话的同 时以较低的系统复杂度 (低成本) 实现了立体图像拍摄功能。 显然, 本发明通过可旋转摄像头的设计解决了相关技术中无法在一台手机上同时 实现视频通话和立体图像拍摄的问题, 从而在不增加硬件的情况下在一台手机上同时 实现视频通话和立体图像拍摄等功能, 大大提高了系统硬件资源的利用率。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
